Youkamoo 4.4mm Balanced Replacement Upgrade Cable Compatible for Sennheiser HD650, HD600, HD660S, HD660S2, HD580, HD58X, Massdrop HD6XX Headphones Upgrade Cable

This is a perfect quality-of-life (and feature) upgrade for the HD 6XX/650. A much better feeling cable than the OEM, with additional versatility in its ability to connect to balanced outputs. Lives on my 6XX now; when I want to listen single-ended I just use an adatper rather than going back to the pretty awful OEM.

Feels very premium, connectors are a tight fit and there’s no noise or interference. I’ll let it known if anything else comes up.

This cable is a very good complement to my FIIO BTR15 DAC/AMP. The 4.4mm balanced connection with my Sennheiser 6XX headphone helps bring out more details and bass extension I never experienced before.

bought 2 of them over the last two years and they both have failed via the cable failing at the connectors (one of the three smaller cables will rip). Lowest price for 4.4mm balanced though so you get what you pay for. Might be worth investing alittle more for a better cable and I will be getting one with a braided cable to see if that helps with this issue however

Purchase these for my Sennheiser HD 6xx headphones & Hiby R4. They do the job....but they're just basic quality. I've only had them for a few weeks and I can already tell they're not going to last very long... let's see how long. I Will update this review.

This is a really great cable.No microphonics. The assembled cable is quite flexible. The jack is high quality. The looks are really good. Left side is left side and right side is right side.You can't ask for more.

The plastic is flimsy and dreadful it broke completely in no time. On top of that, the soldering is poorly done, adding to the overall lack of durability.

Quality 4.4mm balanced cable for HD600s. Cannot go wrong with this cable!
